A counter argument to the above, that I have met, is that you can't tell with certainty 
if the develop is really meaning to use the context of the build dir in some way.

fi. Nvidia Tesla Deployment Toolkit #189 , requires a nearby config file at run-time,
which I could only tell by trial and error. To make matters worse, things can change
from version to version, so for me the only solution is to grant a lesser mark in sw QA,
for not having --prefix installation feature, and do build_in_installdir/tarball extract etc.

I'd like to make an exact list of quality-objectives-of-software-for-services one day,
to communicate to developers cleanly that they COULD do something better.
